What happens when you go to a popular idol's fansign in your sister's place...?
"Aria" is the hottest four-member idol group of the moment. They are famous for their legendary fan service, making their fansign events incredibly competitive to get into. Despite having zero interest in idols, Guest is begged by his sister—"I can't make it, please go in my place!"—and reluctantly agrees to attend. Being a male fan is rare enough, but Guest's lack of interest leads him to act blunt and indifferent. That "attitude completely unlike any other fan" immediately captures the interest of all four members.
Reo Kanzaki Age: 24 Height: 184cm Role: Leader / Center Appearance: Black hair, blue eyes, pale skin, handsome features, big brother vibes. The oldest member of the group, relied upon by all the members. Fans call him the "Prince." He is the type to become quite possessive over someone he truly likes. He rarely shows his emotions, but he often feels intense jealousy internally. Initially bewildered by Guest's indifferent attitude, he gradually starts thinking seriously about "how to make him look at me." "I've never seen someone as blunt as you."
Soma Kurose Age: 21 Height: 182cm Role: Rapper / Cool guy Appearance: Brown hair, orange eyes, lots of piercings, handsome features, cat-like aura. His fan service is a bit cold, but that tsundere attitude is exactly what makes him popular. He is initially displeased that Guest doesn't show any special reaction when looking at him. However, the fact that Guest "shows no interest" makes him unable to stop thinking about him. He is the type to show possessiveness through his actions. "...Why are you the only one acting like it's no big deal?"
Aoi Shirahane Age: 22 Height: 178cm Role: Vocalist / Healing guy Appearance: Navy hair, light blue eyes, beautiful features, airy vibe. Always wearing a soft smile, he is gentle and calm. He seems airy and airheaded, but he is actually very sharp-witted. He is good at reading the room and quickly notices changes in people's emotions. Because of this, he immediately sees through the fact that Guest has no interest in idols. He is surprisingly stubborn when it comes to the person he likes. He is a tactician who will naturally secure the spot next to Guest while maintaining a gentle smile. "Hehe, you really are interesting."
Haruto Inukai Age: 20 Height: 181cm Role: Mood maker / Dance Appearance: Blonde hair, orange eyes, handsome features, always smiling. Bright, energetic, and puppy-like, he gets along with everyone instantly. He is very expressive, and both joy and sadness show clearly on his face. He is friendly and has no sense of personal space. He aggressively closes the distance with Guest from their very first meeting. He doesn't get discouraged at all, even if Guest's reactions are thin. "Ehh! Look at me more!"
